What is a multi-plane barcode scanner?

Where the single-line laser only has a single laser beam which must be aimed directly at the barcode, especially in the case of most handheld barcode readers, the omni-directional barcode scanner shines laser beams in every direction making it nearly impossible for you to not get an accurate reading. Omni-directional or multi-plane scanning is when the scanning paths of the beam form a pattern such that one or more scanning paths necessarily capture the entire barcode regardless of which way it is oriented.

Why choose a multi-plane scanner with a scanning scheme in all directions? For example, the Mindeo multi-plane desktop imager scanner.

The reason for this choice is clear. With multi-plane omnidirectional scanning, it is not necessary to position the barcode in the scanning field. In linear scanning, the beam moves along only one path, so the path and barcode must be positioned so that the scan path passes through all the code symbols. In multi-line scanners, the scanning field is covered by a network of 20-25 intersecting trajectories. This can be valuable when you need to quickly register many different products with different barcode orientations.

Let's discuss in general how the scanner creates a grid from many scanning trajectories. Inside the scanner there is a source of radiation - a laser diode of the visible spectrum. In the center is a rotating polyhedron consisting of shaped mirrors. Mirrors reflect the beam differently because they are installed at different angles. When rotating the polyhedron, the trajectory of the reflected laser beam forms an arc. The number of arcs is determined by the number of mirrors of the polyhedron. The moving laser beam is then passed through a series of fixed mirrors creating "frames" of the scan. By multiplying the number of mirrors of the polyhedron by the number of frames, we get the number of scan trajectories. For example, 4x5=20. The angles of the mutual location of the frames are determined based on the need to ensure the presence of a grid of trajectories in the entire space of the scanning field. The result is a dense network of intersecting scan paths, which ensures that the barcode can

Advantages of the multi-plane scanners

Omnidirectional scanners are also better at reading creased or partially damaged barcodes, as well as barcodes with poor print quality. Multi-planes include presentation desktop barcode scanners, fixed scanners, and scanners built into supermarket checkout counters or self-service kiosks. Stationary scanners are better when there are no restrictions on the size of the cash register and the main requirement is high throughput with a large number of goods. Retail trade is not the only area of application of such scanners. Built-in scanners are used for automatic access control systems, attendance ocntrol systems, and document processing.

They are not built into the cash register, but thanks to the small area, presentation scanners can be installed almost everywhere. Such scanners are small in size and are mainly used as stationary ones. If necessary, they can be used in hand mode for reading heavy goods in the shopping trolley.

Do you need a multi-plane scanner?

To answer this question, determine whether any of the following are the tasks you are dealing with:

• A large flow of goods;
• Need for high-speed reading;
• Lack of a clear orientation of the barcode in relation to the scanner;
• Availability of low-quality barcodes.

Mindeo multi plane omnidirectional scanners

Mindeo multi-plane scanners are distinguished by their quality of reading and decoding barcodes.

Mindeo multi-plane image scanners recognize linear 1D and two-dimensional 2D barcodes (including PDF417, QR code and Data Matrix). They read information from any media, including glossy surfaces and screens of mobile devices. Unlike laser scanners, omnidirectional imagers recognize even damaged, dirty and poor-quality barcodes. Photoscanning technology from Mindeo allows you to read data without long positioning.
